I was wondering how can I help the development of these tools. I have not much time, but if I see a bug and I can fix it, or I can do an improvement to any of the Linux Mint tools, I would like to send my changes.

The source code for all the Linux Mint tools is hosted on GitHub, here: https://github.com/linuxmint. If you create a GitHub account, you can fork the code of the Linux Mint tool you want to work on to your own account. Then fix the bug or implement the feature. Once you are satisfied with the change, you can do a pull request to the Linux Mint developers to request them to integrate your changes.

GitHub has a Code School, where you can learn in 15 minutes to work with Git. It's here: http://try.github.com/.

For further assistance, come join the Linux Mint and contributing developers on the IRC. Open XChat from the menu to automatically join the #linuxmint-chat and #linuxmint-help channels, and then in either type:
